Magnesite chrome block imagwiritsa ntchito magnesia abwino ndi chromic oxide ngati zopangira, zopangidwa ndi makina osindikizira apamwamba ndikuwotchedwa kutentha kwambiri. njerwa za magnesia chrome zili ndi mawonekedwe a kristalo wamkulu komanso kulumikizidwa kwakukulu kwachindunji. ndi njerwa zamoto za maginito za chrome zimakhala ndi mphamvu yabwino yosweka komanso kukana kukokoloka kwa asidi ndi zinthu zochepa zamchere. Magnesite chrome block ndiye njira yabwino yopangira njerwa zopangira ng'anjo yamoto, ng'anjo yamagetsi, ng'anjo yamagalasi, ng'anjo yosungunuka ndi ng'anjo ya simenti yozungulira.
Chifukwa cha njerwa za magnesia chrome, njerwa ya chromium ya magnesia imagawidwa kukhala njerwa wamba ya magnesia chrome, njerwa yolumikizidwa mwachindunji ndi magnesia chrome njerwa, njerwa zomangika za magnesia chrome, njerwa yolumikizidwa ya chrome ndi zina zotero.
Njerwa za Magnesia chrome zimapangidwa ndi zinthu zomwe zimagwirizanitsidwa ndi sintered, ndikuchotsa zotayirira zomwe zimayambitsidwa ndi kufalikira popanga spinel ndi zomwe MgO ndi Cr2O3, Al2O3 kapena FeO. Kuphatikiza apo, palinso njerwa zoyaka moto za magnetsite chrome monga chipika chosawotchedwa cha magnesite chrome chopangidwa ndi inorganic magnesia saline solution. ndi njerwa zosawotchedwa za magnesia chrome ndizosavuta komanso zotsika mtengo. Mtundu uwu wa njerwa ya magnesia chrome imakhala ndi kukhazikika kwakukulu kwa kutentha, koma kutentha kwake kwakukulu kumakhala kochepa kuposa njerwa yopsereza ya magnesia chrome.

Njerwa ya Magnesia Chrome imagwiritsidwa ntchito kwambiri m'mafakitale azitsulo, monga kumanga ng'anjo yotseguka, ng'anjo ya ng'anjo yamagetsi, kuchokera ku ng'anjo yamoto ndi mitundu yonse ya ng'anjo yosungunula yopanda chitsulo. Magnesite chrome block imagwiritsidwanso ntchito poyatsa ng'anjo ya simenti yozungulira komanso chipinda chowongolera chamoto wagalasi.
RS refractory fakitale ndi katswiri wogulitsa njerwa za magnesia chrome zomwe zidakhazikitsidwa koyambirira kwa 90s zaka makumi awiri. Fakitale ya RS refractory yakhala imapanga njerwa zamoto za maginito chrome kwazaka zopitilira 20. Ngati muli ndi kufunikira kwa chipika cha maginito chrome, kapena muli ndi mafunso pa njerwa za magnesia chrome zokhudzana ndi zizindikiro zakuthupi ndi zamankhwala, chonde titumizireni kwaulere. Rs refractory fakitale monga katswiri wopanga njerwa zamoto ku China, ili ndi zabwino zina zampikisano motere:
